As digital technologies continue to advance, so do the threats that target sensitive information and critical infrastructure. Cybersecurity encompasses a range of practices including risk management, network security, encryption, firewalls, and user education. It plays a vital role in ensuring data privacy, maintaining trust, and enabling safe use of technology across personal, corporate, and governmental environments.
